SEWlNG-MACHlNE-NEEDLE CLAMP.

SPECIFICATION forming part of Letters Patent No. 299,847, dated June 3,1884.

Application filed December 18, 1883.

' a citizen of France, residing at Paris, in the Republic of France,haveinvented an Improvement in Sewing-Machine Needles and their Holders,(for which I have obtained a patent in Great Britain, dated November 26,1883, N 0. 5, 521; France, dated November 8, 1883, and Belgium datedNovember 24, 1883,) of which the following is a specification.

In sewing-machines, whether for lock-stitch, chain-stitch, or for otherkinds of stitch, it is of great importance thatv the side of the needleat which the loop is engaged by the shuttle, hook, or other organ shouldmaintain a constant position relatively to the movement of that organ,notwithstanding that needles of 1 various sizes may be used in themachine.

My invention relates to a construction of the needle and its holder,whereby the accuracy of position of the loop side of the needleisinsured and facility is given for removing or inserting needles ofvarious sizes without varying this position, as Iwill explain, referringto the accompanying figures, which are drawn to enlarged scales in orderto sh ow details more clearly.

Figure 1 is a vertical section, Fig. 2 is aside elevation, and Fig. 3 isa sectional plan, of the needle-holder, and Figs. 4 and 5 are front andside views of the plate fitted therein, these five figures being drawnto a scale of about four times the natural size. Fig. 6 is a plan of theneedle-head, showing the relative positions of sections of needles ofvarious sizes, this figure being drawn to a scale of aboutsixteen timesthe natural size. I

The stem A of the needle-holder is at its lower end turned to fit aring, B, and has a hole, 0, the size of the needle-head bored up itscenter. It is also slotted across to receive a flat plate, D, whichtrespasses on a segment of the circular hole 0, and has a littleside-play in the slot between the two limbs f f of the stem. The ring B,to which may be attached a thread-guide, b, is held on the stem A by ascrew, 6, which passes through a free hole in the ring, and is screwedinto one of the limbs f. The ringB is furnished with a setting-screw, E,by screwing up which the limbs ff of the stern are forced toward eachother, so as to (No model.) Patented in France November 3, 1883, No.158,344; in Belgium November 24, 1883, No. 63,321, and in EnglandNovember 526, 1883, No. 5,521.

pinch the parts between them, like the jaws of a' vise. The plate D ismade with two projecting shoulders, (Z d, which, lodging onthe upperedge of the ring 13, prevent the plate D from dropping out of the slot.The head of the needle, as shown in Fig. 6, is cylindrical, with asegment cut off one -side, so as to present a flat face, 0.

Needles of various sizes are made with heads, which are all of the samesize, and with their shanks eccentric to the head, but all tangential tothe plane of the fiat side 0, as indicated by the several dotted circlesin Fig. 6, each of those circles representing the section of aneedle-shank. Vhatever, therefore, be the size of needle thusconstructed, its one side, at which the thread-loop is acted on, is invertical line with the face 0. On slackening the screw E the head of theneedle can be inserted into the holeO of thestem until it butts againstthe top of the hole, as shown in Fig. 1, and then by screwing up thescrew E the needle becomes firmly gripped, the flat side of its headlying against the face of the plate D.

Having'thus described the nature of my invention and the best means Iknow of carrying it into practical operation, I claim- 1. Thecombination of a sewing-machine needle having its circular head providedwith a fiat face tangential to the circular section of its shank, with aneedle-holder bored to re ceive the needle-head, and provided with atransverse slot, a fiat plate held in the slot to bear against the flatside of the needle-head, and means for forcing the plate and needleheadtogether, substantially as described.

2. The combination of a sewing-machine needle having its circular headprovided with a flat face, 0, tangential to the circular section of itsshank, with a holder having a slot to form limbs f, and bored to receivethe needlehead, a flat plate, D, arranged in the slot to bear againstthe flat face of the needle-head, and devices for forcing the limbstogether to grip ,the needle-head and press its fiat face against thefiat plate, substantially as described.

I 3. The combination of a sewing-machine needle having a circular headprovided with aflat face, 0, with aholder bored to receive theneedle-head, and provided with a transverse slot to form two limbs, f,the ring B, attached to this specification, in the presence of two subtoone of the limbs, and provided with a screw, scribing witnesses, thislst day of December, E, and a flat plate arranged in the slot to bear A.D. 1883.
